Build me an auction sniper

Need a simple auction sniper targeting one specific auction, greatcollections.com. This auction sells items every Sunday. Their lots sell every few seconds on Sunday. I don't want to be sitting around bidding on lots manually. So I need a sniper to automatically execute my bids a few seconds before lots end.
There are many eBay sniper programs out there. Just google them to understand their functionality. Here is a sniper that I was using, but is not working anymore. Thank you.
